Definitions

• the present invention relates to a composition, intended in particular for making up and/or caring for the lips and the skin, comprising at least 10 % by weight of water, at least 10 % by weight of a silicone resin, at least one non-volatile silicone oil and optionally additional particular hydrocarbon-based oils, and also to a process for treating and/or making up keratin materials, in particular the lips.
• compositions for making up and/or caring for the lips in particular fluid compositions such as liquid lipsticks, which are stable and endowed with satisfactory properties in terms of application (glidance on application, ease of spreading and fineness of the deposit), but also in terms of the makeup effect of the deposit on the lips, for instance the absence of migration of the deposit, preferably without becoming tacky, is an ongoing objective.
• formulations corresponding to liquid presentation forms conventionally comprise oils, which in particular provide gloss, optionally waxes for structuring the compositions, fillers especially for thickening the composition, film- forming polymers, and dyestuffs.
• liquid lipsticks must be sufficiently fluid to be easily applied, but not too fluid, so as not to degrade the stability of the composition (pigment sedimentation) and the ease of application (running).
• the deposit is relatively thick, thereby giving it a more or less tacky nature, especially induced by the use of these oils and of the polymers present. This nature may be reflected especially by adhesion of the made-up lips to each other, causing the user an unpleasant sensation in terms of comfort.
• Liquid lipstick compositions have quite recently appeared on the market, in the form of direct or inverse aqueous emulsions. When they are applied, they provide a fresh effect, and are sparingly tacky or non-tacky, and comfortable, and remain so once deposited. They also make it possible to obtain a homogeneous, sufficiently glossy deposit which has satisfactory persistence and transfer resistance.
• compositions Nevertheless, it is desired to further improve the persistence of these compositions, and also their transfer resistance, without, however, losing any gloss on application or any comfort. Specifically, it is not uncommon to find that such compositions have the drawback of leaving either a matt deposit or a deposit which is more uncomfortable since it is very present on the lips (with an impression of reduction of the mobility of the lips), often accompanied by a sensation of dryness.
• compositions that can be applied both to the lips and to the skin, in particular to the face and more precisely the cheeks.
• compositions in particular liquid compositions, which can produce a deposit whose persistence and transfer resistance are improved without any loss of comfort are thus sought.
• non- volatile hydrocarbon-based oil in a content of less than 15% by weight, relative to the weight of the composition; said non- volatile hydrocarbon-based oil(s) being chosen from:
• the film deposited on the lips has the advantage of being thin and affords a fresh effect on application, without significant migration into the wrinkles and fine lines.
• composition is stable, easy to apply, comfortable on application since the deposit obtained is sparingly tacky or non-tacky, and remains so once in place. Moreover, the deposit does not give an impression of dryness of the lips.
• the deposit obtained by applying the composition according to the invention has satisfactory gloss.

• composition according to the invention is advantageously in a liquid form.
• liquid means a fluid texture, the viscosity of which at 25°C is more particularly between 0.05 and 10 Pa.s, preferably between 0.1 and 8 Pa.s.
• Protocol for measuring the viscosity The viscosity measurement is generally performed at 25°C, using a Rheomat RM 100 viscometer equipped with a no. 2 or 3 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition, at a shear rate of 200 revolutions/min (rpm). Protocol for measuring the stability:
• a composition is stable when substantially no phase separation is observed, or any sedimentation of the solid particles if the composition comprises any, when the following protocol is performed:
• Centrifugations are performed at room temperature on samples of composition introduced into sterile, 15-ml graduated plastic centrifugation tubes made of propylene, with a conical end and a stopper (ref. Biologix 10-9152) to be filled with 8.6 g of composition).
• the measurement is more particularly performed 24 hours after making the composition.
• the composition is in the form of a composition whose aqueous phase is the continuous phase and whose oily phase is the dispersed phase (oil-in-water direct emulsion).
